A spate of false security alarms is keeping the Heelers on their toes. Tom is becoming increasingly frustrated with the owner of the alarm company, Roland Halliday, and his inefficiencies. If the Heelers are constantly being called to false alarms they will have little time left to pursue real crimes. Meanwhile, Adam is involved in a more pressing matter. His mate ""Croc"" Perry has been involved in an incident at the local fast food shop. Adam keeps him out of hot water and also makes amends with the shop proprietor, earning his gratitude—Adam's burgers from now on are free. Tom is unimpressed with Adam for exercising poor professional judgment by associating with the likes of Croc. Tom's disaffection worsens when Adam brings in free hamburgers for all the Heelers. In Tom's view accepting ""gifts"", no matter how small, is skating a little too close to corruption; nothing is free in this world. Nick also knows Croc: he is one of the local boys who Nick has been trying to help. Howev
